Amazon has a lot more choices on the convertor but let's cover a VERY important issue with Samsung today. Ready?

If the source is HDMI, Samsung does not pass HD audio, So this creates a situation where nothing works.

It may be too much of a challenge for some but let's go over the fix. On the source send only stereo, PCM or 2.1 audio. You may have to test that a few times. Also for the TV set it to stereo or PCM. Test again. In APPs such as Netflix always set it to stereo audio.

That should clear up the encoding issues and the non-passing of HD audio by not sending HD audio in the first place.

I have yet to find this to be an amplifier issue.
